Handmade using wonderfully "sun-tanned" leather and an innovative design that lets you change from backpack to cross-body bag to briefcase whenever you want! We have lined it using royal green, military canvas which works well with the deep tan of the leather. The size is perfect for a 13" laptop to fit into the internal canvas sleeve although a 15" laptop will fit in the main compartment (or all your other essentials). There is also an internal and an outer zip pocket. It has been handmade to the highest standard to make sure it looks great in all of it's carrying options - this is 3 leather bags in 1 beautiful all rounder! We should really call it the Leather Laptop Backpack Briefcase but we prefer The 3 in 1! Large size.
